hannspree hsg1064: looking for replacement parts, and couple questions

[onewolf]

Hello!

I'm brand new here. Great site.

So, someone was throwing out a much nicer monitor than the one I'm using, a hannspree hsg1064. He didn't know what was wrong, so I plugged in and found that the screen appeared normally for about 5 seconds, then went black. Searching for this symptom lead me here, and to your very helpful FAQ on the subject.

I don't have a multimeter (yet) so I figured I'd check the lamps. See the pictures below and you can see what I found

Anyway, I've never done this kind of thing before (only thing I've ever done with a monitor is plug one in). As you can see in the pictures, there's a bunch of oxidation on the frame, and some sort of white stuff around the breakage. What is that stuff?

Does having broken CCFLs cause any other problems that I should look into before replacing the broken lamps?

Is there a place that you guys recommend for buying CCFLs? I didn't find anyone selling specifically for my monitor model, are all 25" CCFLs alike?

I assume that the connectors that attach the CCFLs are specific to the board, so what comes with the lamps? Like lengths of wire or something, or do I need to solder onto contacts on the lamps themselves? Seems sketchy getting that much heat near the tubes... If I do need to do that, what sort of wire should I use?

Lastly, is there anything I should know as a first-timer replacing these things?


Thanks for bearing with my beginner's questions, and thanks a ton for reading. I appreciate it!

For replacement CCFLs, any of the same size will do, they are standardized. The lamps come with bare ends - you reuse the wires that are already in the monitor.

You are to put some small heatshrink on the wires and slide it down. Solder the wires to the new lamp. Drag heatshrink over solder connection and shrink it using hot air, your soldering iron or any other heat source. Re-assemble panel.

Edit: In most monitor and laptop panels you can replace the CCFLs without opening the screen up entirely. You can cut the frame at the corners where the lamps are and just pull the lamps out. This method is recommended whenever you can use it as it reduces chances that dust will get into the screen.
